The $99 AI Visibility Toolkit includes one Brand Performance domain, 25 tracked prompts, 300 daily AI Analysis queries, 1,000 daily Prompt Research queries, 100 AI Search Site Audit pages, and 10 CSV exports per day. Semrush One adds the SEO Toolkit and begins at $199 per month.

Foglift Launch is $49/month. That is $50/month below the standalone Semrush AI Visibility Toolkit and $150/month below Semrush One Starter. The products are not feature-identical: Semrush carries the broader SEO research suite, while Foglift includes the focused Technical Audit, five-engine monitoring, recommendation, crawler, referral, and developer workflow.

The Bottom Line

Foglift is the better focused choice when the job is to diagnose a page, monitor answers, prioritize fixes, and connect the result to observed crawler and referral evidence. Unlimited single-page Technical Audits cost $0. Launch costs $49/month and adds daily five-engine monitoring, weekly 100-page full-site audits, REST API, CLI, MCP, webhooks, and batch scanning.

Semrush is stronger for the broad search stack. Its SEO Toolkit carries keyword, backlink, rank-tracking, competitor-research, and large-crawl workflows. Its AI Visibility Toolkit adds a 317M+ prompt-and-response research layer, custom prompt tracking, Brand Performance, competitor research, and AI Search Site Audit. Semrush One packages the SEO and AI visibility jobs together.

The measurable distinction is the evidence model. Foglift keeps technical readiness, answer mentions, provider-returned citations, crawler fetches, recognized referrals, and Google clicks separate. A crawler fetch alone does not prove a citation or referral. That separation makes it possible to see whether an engine can retrieve a page, whether it selects the page, and whether a person clicks through.

The tools can be paired. Use Semrush for keyword, backlink, rank-tracking, and advertising research. Use Foglift for the audit-to-answer-to-crawler-and-referral loop, especially when Claude monitoring, a permanent free Technical Audit, and developer access from $49/month matter.
